PARKER PARKER Duofold Stamped 18K 750 on the nib. I believe I purchased this in the 90s. This item was found at my parents' house. I am not familiar with fountain pens, so I would appreciate it if you could judge the details and condition from the photos (there are fine scratches on the black part of the grip, and some signs of use are visible on the nib). * If you need any other photos, please feel free to comment. If you are able to maintain it yourself, or if you are knowledgeable about fountain pens and are interested, please consider purchasing it. I have priced it based on the market price of similar models, but please feel free to consult with me if you have a desired price.
